Nanotechnology!

Nanotechnology is the study of manipulating matter on the molecular level at the nanoscale (1-100 nanometers), used in the fields of science, engineering, and technology and their varients.


Uses of Nanotechnology!
Cosmetics:
  • Moisturizers, lotions hair-care products, make-up, and sunscreen
  • L’Oreal lotions and creams manipulate nanoparticles for "visible results"
  • Healing and repair of skin tissue
  • Prevent graying hair and hair loss
  • Antiperspirants--used to block odor and sweat in common deodorants/antiperspirants, such as Secret brand
  • New technology, still a minority in most facial and body creams or moisturizers

Sports:
Nanotechnology is a huge use in sports today especially with equipment such as:
  • Wilson products such as tennis rackets are now twice as stable and twenty-two percent more powerful from the use of nanotubes, and Wilson also uses a nano‐composite to replace the titanium crown used on current golf clubs to lower the weight increasing the power of the hit.
  • Speed Cars where Nanotec-USA applied their Nano-Bionics treatment to the Nish Motor Sports’ speed car using fifty percent less than usual mixture of Nitro Methane fuel mixture, yet the cars managed to go a speed 37 miles per hour faster than their previous top speed.
  • Competitive swimwear such as the Speedo LZR Racer, which had been banned after the 2008 Olympics.
  • Nanotechnology allows scientists to create new, ultra-lightweight swimwear that needs to be approved by FINA to help swimmers glide through the water.
  • Tests have shown that the amount of water absorbed has been reduced to only two percent fabric weight rather than the fifty percent absorption in the previous materials used.

Medical
  • used in drug therapies or "smart drug", these drug therapies cause fewer side effects and more effective than traditional therapies
  • aid in formation of molecular systems
  • regeneration or replacement of body parts that are lost to infection, accident, or disease
  • employing nanoparticles to deliver drugs, heat, light, or other substances to specific types of cells, such as cancer cells
  • reimplication of the tissue

Application of Silver Nanoparticles!
Application in HIV/Aids Virus Prevention
  • Silver nanoparticles of certain sizes can attach to the HIV-1 virus and prevent it from bonding to host cells.
  • could be a new treatment for the virus
  • big step in possibly preventing and making the HIV-1 virus extinct in future medicine and society (diagnostic applications)

Antibacterial Applications
  • Silver nanoparticles are included in wound dressings for their antibacterial properties to help fight off infection.

Diagnostic Applications
  • Silver nanoparticles are used in biosensors and numerous assays where the silver nanoparticle materials can be used as biological tags for quantitative detection.

Drawback of Silver Nanoparticles!
  • Although Silver nanoparticles are helpful in fighting off infection, there are some drawbacks. For instance, Silver nanoparticles kill benefical bacteria in the water which affects the environment in a negative way.
